    The status of native freshwater fish biodiversity in the Perth and south-west catchments is largely unknown. A recent pilot survey of the area found that native fish are absent from many water bodies.

    With funding from the State NRM Program, the Department of Fisheries surveyed the distribution, abundance and genetic diversity of native fish in freshwater bodies from Geraldton to Busselton.

    Information from this survey will help focus conservation, rehabilitation and restocking efforts for water bodies and species at greatest risk.

    Fish were also selected for inclusion in breeding programs and hatchery facilities were upgraded to increase production capacity.

    Investment: $ 500 000
    Delivery organisation: Department of Fisheries
    Project duration: January 2010 - March 2011
    Location: Perth and south-west catchments between Busselton and Geraldton and east to Northam

    Major project achievements

    • Distribution and abundance of native freshwater fish in Perth and south-west catchments determined.
    • Fisheries freshwater fish website developed to make this information widely available and to focus and prioritise management and rehabilitation efforts.
    • Species and water bodies at most risk of extinction or loss of biodiversity identified and prioritised.
    • Genetic diversity of endemic species determined.
    • Genetic lines of fish suitable for restocking priority water bodies identified, collected and included in the hatchery breeding program.
    • Modifications made to hatchery infrastructure to increase native freshwater fish production for restocking.
